GATE-OPENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 337,618. dated March 9,1886.

Application filed August 6, 18857 Serial No. 173,743.

' specification.

The object of the invention is to provide an improved device of that class by which a gate may be opened by the vehicle about to be driven through it and closed by the same vehicle without the driver descending from his seat; and it consists in the peculiar combinations and the novel construction and arrangement of parts, all as more fully hereinafter described and claimed.

Figure l is a perspective view showing my improved gate-opening device applied to an ordinary farm-gate. Fig. 2 is a detail showing the form of the support on which the gate is hinged and through which the vertical spindle passes. Fig. 3 is a detail of the holdfast for the latch.

A is the gate, provided with hinges B, securely bolted to it and designed to fit over the hollow supports 0, which are securely fastened to the gate-post D, as indicated.

E is a vertical hinge-rod or spindle passing through hollow supports 0, and having a crank, a, formed on its top end, as indicated. This crank is attached to the block or weight F by the cord or chain, 1). This cord or chain passes over a swivel-pulley, d, which is arranged and located as indicated, so that it will turn uponits pivot to accommodate the position of the crank a on whichever side of the gate A it may atthe time be pulling. The block or weight F is carried on suitable guiderods, G,which are secured to the gate A, as indicated, and the weight is intended to be so connected to them thatit will slide freely vertically when drawn upon by the cord orchain b.

H is a quadrant or segment of a pulley attached to the end of the spindle or hinge-rod E.

I are two double-cranked trip-rods, located one on each side of the gate A, and carried horizontally in suitable bearings, as indicated, the cranks being set at 'right angles to each other and arranged so that when one is horizontal and out of the way, the other crank on the same trip-rod is vertical and projects (No model.)

above the ground. On the end of each double-cranked trip-rod I fix apulley, J, and connect the said pulleys on opposite sides of the gate by the rod and chain K, so thatwhen one pulley is caused to revolve a corresponding motion is imparted to the other pulley.

L also represents rods or chains to connect the pulleys J to the quadrant H, as indicated in Fig. 1, so that when either of the doubleended trip-rods I is caused to rock upon its bearing a corresponding motion is imparted to the quadrant H, and as this quadrantis connected to the spindle orhinge-rod Ea corresponding movement is imparted to the said spindle.

Mis a double arm fixed to the spindle or hinge-rod E, and connected, as indicated, to the spring-latch N by the rods or chains 0.

P is a notched hasp, into which the springlatch N fits.

Having nowdescribed the general construction of the parts involved in my invention, a few words will sui'fice to explain its operation. I will assume that the vehicle is being driven toward the left-hand side of the gate A. The wheel will then strike the crankfon the double-cranked trip-rod I, causing the trip-rod to rock on its bearing and draw upon the rod K, which is connected, as before described. to the two pulleys J. Consequently the pulley on the opposite or right-hand side of the gate is caused to revolve, and will therefore draw upon its rod L, which is connected to the quadrant H, fastened to the spindle or hingerod E, thereby causing the said spindle or hinge-rod to revolve in the direction indicated by the arrow. As the spindle or hinge-rod moves in this direction, the weight F will be raised, and at the same time the springlatch N drawn back out of the notch in the hasp P, when the gate will naturally swing back in the direction indicated by the arrow to the holding-post Q, where a corresponding hasp, P, is located, asindicated. Byconnectingthespindle E to the gate through a movable weight, F, the movement of the gate is produced in a quiet and gradual manner, avoiding the shock to the various parts, which would occur if the double-cranked trip-rods I were connected directly toa fixed portion of the gate. By forming the hasp P as shown in Fig. 3-that is to say, placing a piece of springrubber, g, be- I and the double-cranked trip-rods I, connected hind it-the shock of the gate in closing is entirely overcome.

What I claim as my invention iS-- 1. lhe combination of the gate A, hinged upon hollow supports, the hinge-rod E, passing through said supports, the movable block or weight F,eonneeted with said rod, the quadrant H, secured to said rod, and the doublecranked trip-rods I, connected with said quadrant, substantially as and for the purpose specified.

2. The combination of the gate A, hinged upon the hollow supports G,the vertical hingerod E, having a crank-arm, a, at its top,\vhich passes through said supports and is connected to the movable block or weight F, as described,

to the hinge-rod E, substantially as and for the purpose specified. v

3. The post D, hollow supports 0, attached thereto, vertical hinge-rod E, and the gate A, hinged upon said hollow supports, and the double arm M, formed on said hinge-rod, in combination with the spring-latch N, connected to said arm and arranged to engage with the hasp P, substantially as and for the purpose specified.
